The Vaonis Light Pollution Suppression Filter allows you to improve the quality of your photos when observing in the city or suburbs. It attenuates the effects of light pollution and thus increases the contrast between the celestial object being photographed and the background sky. The broadband filter blocks Na (sodium) and Hg (mercury) wavelengths emitted mainly by urban night lighting or undesirable natural light (atmospheric oxygen radiation, etc.), while allowing the main wavelengths from celestial objects. The exterior of this filter comes in a premium Black finish.
Anti-Light Pollution Filter
The anti-light pollution filter is particularly useful for improving the brightness of deep sky objects, nebulae, star clusters, galaxies, etc. It is especially effective on emission nebulae because of the filtered wavelengths. Designed specifically for the Vespera lens, it fits easily and discreetly into the optical arm. The lens ring that holds the CLS filter is equipped with an electronic card that allows Vespera to detect it. Some of the examples of emission nebulae are Bubble (NGC 7635), Crescent (NGC 6888), Eagle, Elephant’s Trunk (IC 1396), Flame (NGC 2024), Lagoon (M8), North America (NGC 7000), Omega (M17), Orion (M42), Pacman (NGC 281), Rosette (NGC 2237), Tarantula (NGC 2070), Thor’s Helmet (NGC 2359), Trifid (M20), and Tulip (Sh2-101).
Instruction of Use
Remove the standard Vespera lens ring and insert the light pollution filter until you hear a click. To verify that the light pollution filter is properly positioned, connect Vespera to your mobile device and launch the Singularity app. In the Space Center and then on the instrument screen, the word CLS is shown. The filter is of limited use when observing the moon, stars, and planets, which are very bright objects. It is designed for use in urban or suburban areas or in the presence of ambient light. It does not have to be used in an environment with ideal viewing conditions. Because the filter allows less light to pass through the sensor, the stacking speed may be slightly affected. The light pollution filter is ineffective against LED lighting.
Direction of Use
Do not expose the filter to direct sunlight. Store the filter in its box after each use to avoid dust buildup. If you notice any streaks or dust, gently clean the filter with an optical wipe, microfiber cloth, feather duster, or air blower. Do not attempt to open the lens ring that contains the filter.
